Application filed April 14, 1917. Serial No. 162,044.

To all whom it may concern:

the hopper in whatever position of vertical adjustment the hopper may be placed, said means being of such character that it may be manipulated so as to permit perfect freedom of vertical adjustment of the hopper upon the supporting tower.

The accompanylng drawings illustrate our invention. Figure 1 is a side elevation of an apparatus embodying our invention; Fig. 2 a perspective detail of a section of the tower, the elevator, the receiving hopper, and our attachment; Fig. 3 a fragmentary detail of theouter end of one of the switches; Fig. 4 an elevation of the switch mounting; and Fig. 5 a plan.

In the drawings, 10 indicates a tower structure of any desired form provided with vertical ways 11 which form a guide for the elevator 12 which carries a dumping bucket 13 provided with rollers 14 at its forward upper corners. I The bucket 13 is of that common type which is normally counterbalanced on the side of its axi 15 opposite rollers 14 so that the bucket itself, as well as the loaded bucket, is in a normally stable condition on the elevator 12. Mounted so as to be vertically slidable upon towerlO is a hopper carriage 21 which may be vertically llfted by means of a lifting cable 22 attached to its upper portion. On this vertically movable carriage 21 is secured a hopper 23 and in common practice the carriage 21 may also be extended to carrya boom seat 24 and a. tackle block head 25.

Our invention resides in the provision of switches carried by hopper 23 in such manner that they may be readily manipulated to permit the convenient raising and lowering of hopper 23. We attach to the frame 21 just above the hopper 23 a cross bar 30 11p0n which are mounted a series of ears 31 arranged in two pairs. Each pair of cars 31 forms a support for a pivot pin 32 upon which is pivoted a switch 33 said: switch comprising a pair of parallel curv d. brackets 34 spaced apart a' distance sufficient to permit the entry of a roller 14. The lower-track 34 is extended at its front end and attached to its vertical flange is a finger 35 spaced a short distance from the vertical flange of track 34 so as to form a crotch or notch 35 capable of receiving the lower end of a rod 36 carrying a nut or head 37 at its lower end. Each rod 36 has its upper end pivoted at 38 to frame 21 and is preferably formed in two parts connected by a turn-buckle 39.

In operation, the switches 33, being pivoted upon pins 32; may be readily swung to the position occupied by the right hand switch in Fig. 2, where the initial end of the switch is thrown upwardly and entirely outside the vertical plane of the front of the tower 21, so that the switches during the raising or lowering of hopper 23 will clear the tower structure. Whenever the hopper has been brought to a desired position of vertical adjustment upon the tower, however, the switches may be thrown up so as t project their initial curved ends into the tower space in position to receive the rollers 14. The lefthand switch in Fig. 1 is shown in the process of being thrown to active position, the operator slipping the rod 36 into the notch or crotch 35 with head 37 under finger 35 and the vertical flange of the track 33. Under normal conditions it is not necessary to tighten rod 36 in conjunction with the sWitches but this may be done by turn-buckle 39, if desired. When it is desired to shift the hopper upon the tower, the operator has merely to slip rods 36 from crotches 35 and then swing the switches to inactive position during the shifting of the'hoppe I We claim as our invention:

1. In an apparatus for handling slush concrete, the combination with a tower and dumping elevator bucket arranged therein, of a hopper vertically adjustable upon the tower, and a switch movablymounted upon the hopper and movable into active position out of said active position and beyond interference with the tower, and means for holding said switch in active position.

2. In an apparatus for handling slush concrete, a hopper carriage adapted to be mounted upon a vertical tower for vertical adjustment thereon, a hopper carried by said carriage, a switch pivoted upon said carriage and formed for cooperation with a dumping bucket to be mounted in the tower whereby said switch may be projected into active dumping position and withdrawn so as to clear the tower structure, and means for holding the switch in its active position.

3. In an apparatus for handling slush mean? concrete, a hopper carriage adapted to be mounted upon a vertical tower for vertical adjustment thereon, a hopper can led by said carriage, and a switch pivoted upon said oarriage and formed for cooperation with a dumping bucket to be mounted in the tower whereby said switch may be projected into active dumping position and withdrawn so as to clear the tower structure.

In witness whereof we have hereunto set our hands at Indianapolis, Indiana, this fourth day of April, A. D. one thousand nine hundred and seventeen.
